Well, holy crap! 8's out of the box? A 250 mph top speed? That is not all. The new Tesla roadster is said to hit 60 in 1.9 seconds and it will hit 100 miles per hour in 4.2 seconds. Those numbers are so mind numbingly fast please excuse us for being skeptical.
When will it hit the market? Apparently it is being positioned as a 2020 model year car.
The battery capacity is said to be good for 630 miles. Three motors will supply over 7,000 lb-ft of torque.
It will start at $200,000 which for the numbers Tesla is quoting is well worth the money. Hell, it's worth double.
It is going to be very hard to argue against the new Tesla Roadster if it delivers as advertised. The only downside will likely be the heft.

Sport Auto got their hands on two of the world's best track cars and took them to the Hockenheim in Germany for a laptime comparison. You may remember that the Lamborghini Huracan Performante briefly held the Nurburgring production car laptime record.
That was until the 911 GT2 RS took the Nurburgring record with an insane 6:47.3 laptime.
How do they fare on a smaller track going head to head in the same conditions? Like this:
The GT2 RS time is out of this world. It did not just beat every other car Sport Auto tested it crushed them. That includes the Huracan Performante which is the second quickest they have ever tested.
Porsche did not pull any punches. They set out to build the world's top track car and they succeeded.

MotorTrend got their hands on these two German hot rods featuring 3.0 liter twin turbo powerplants. The engine design is quite different however with the 911 GTS 9A2B6 featuring an oversquare flat-6 and the M4 S55 featuring an undersquare inline-6 which BoostAddict previously covered in an engine design comparison article.
That said on paper these cars match up well. The M4 obviously offers greater value but it is heavier and seats four adults. The 911 does not seat four adults but is roughly 200 pounds lighter and of course more expensive. Power is essentially a wash on paper but we really need to see them both on the dyno to know the truth regarding torque curves, spool, and output. Unlike BMW who just changes software for the output gain, Porsche gives you larger turbos with the GTS.
This GTS is rear wheel drive just like the M4 and both have dual clutch transmissions so this is as apples to apples as we are going to get. Ok, let's get to the actual performance comparison!
They get the cars out on the Nurburgring and how can you not love that? Well, they ruin the whole thing by not providing laptimes. WTF is the point here guys? You attend a track day, talk about factory laptimes, and provide no actual performance measures. MotorTrend should never be allowed to take cars on the 'Ring again.
What happens after the big Nurburgring buildup that ends in a whimper? They go on some damp and foggy mountain road and continue to yammer on about their feelings. Where is the Head 2 Head performance comparison gentlemen? You might as well have grandmothers compare these cars.
What a waste of time MotorTrend. Don't call it a Head 2 Head comparison when really it is just story time with Jonny Lieberman and some guy who has an English accent which obviously means he has to know cars. You guys are a joke.

Some JB4 on JB4 action here! BMS (Burger Tuning) JB4 boxes are very popular in the BMW world but recently they started expanded into the Infiniti market due to the new VR30DDTT 3.0 liter V6 twin turbo powerplant.
The results early on for the Q50 models are promising with BMS Alpha tunes showing 413 wheel horsepower. Note, this is not the Red Sport version.
The B58 turbo I6 under the hood of the 440i should be familiar to you and with a JB4 tune and some meth can put out ~450 wheel horsepower.
Interestingly, the Infiniti pulls. They do two pulls and the result is the same with the Infiniti winning although in the second run it's a beatdown.
Why the Infiniti wins in dominating fashion has us scratching our heads.

Some good natured ribbing took place when Weistec recently ran 10's tune only in their W213 E63 AMG S. APR noticed the run of course and mentioned lining up against an APR tuned RS7. Weistec shot back with asking how big of a head start APR would need.
You can read the exchange here:
This of course got us comparing times for both platforms for fun. The truth is the German mid-size sport sedan class is more similar than it has ever been.
The RS7 and E63 both have similar 4.0 liter turbo V8 motors, both are all wheel drive, and both weigh about the same.
It is important to note that the RS7 does have a significant tune only lead. APR gets 10.4 @ 132 with just their Stage I tune out of the RS7.
The truth is the top 1/4 mile car from the previous generation with just software alone was the RS7. It's ironic that the machine with the smallest engine in the class topped 5.5 liter and 4.4 liter rivals from Mercedes and BMW respectively.
The C7 RS7 looks like it will still be the tune only champ compared to the new F90 M5 and W213 E63 S.
Weistec had a good response:
With upgraded turbos the RS7 does not stand much of a chance. Speaking of which, why is the RS7 seemingly stuck tuning stock turbochargers? There still is little in the way of results for 4.0 TFSI's with aftermarket turbo upgrades yet the car has been on the market for years now.
The M177 certainly looks like it has the edge when it comes to the aftermarket in that respect.
We will see what happens and you can count on BenzBoost, AudiBoost, and BoostAddict to bring you all the tuning developments on the respective engine platforms.

So i recently came accross this https://www.hsd-il.com/ website and noticed they use stainless steel to make some really cheap downpipes, unfortuneatly i couldn't find any AMG downpipes there but i found some of theirs listed on Ebay (for AMG). So i contacted them to see what's up and they said they're working on their website and will have it listed. They seem to be legit at my glance but i haven't seen reviews on them, anyone with any experience with HSD-IL?

It is as if someone read our minds. Watching the McLaren 720S leave everything in its dust is getting a bit boring. The car is just so fast in stock form (running 9.7 @ 147) that there are no real challengers as far as stock cars are concerned and it is going to take something stout from the aftermarket to challenge it.
Modified Nissan GTR's can range from 600-2500 horsepower. There are plenty of GTR's that can give the 720S more than it can handle.
The one in the video chosen here has a built motor with ugpraded turbos and on a SuperFlow dyno is making 813 whp compared to the 720S 691 whp. Very close to Dynojet output:
The GTR obviously is all wheel drive and comes with a weight penalty of roughly 650 pounds.
So how does it do?
Just ok. The 720S still pulls from a roll and opens up a lead it holds. The GTR maybe claws back some inches but it loses decisively.
The GTR will up the boost and they will run again. If we were to predict what it takes it looks like the GTR will need about 900 whp to take the 720S. That's insane.

A Hellcat on E85 with bolt ons is capable of some serious power. The video states 700 whp but that would be somewhat weak considering Hellcats can hit 750+ whp with E85 tuning alone. Obviously this Challenger is making big power but it is going up against some stout competition.
Up first is a C7 Corvette Z06 with a heads/cam upgrade also tuned on E85. The Z06 crushes the Challenger. It is simply a beatdown.
What about the Procharged C7? A similar result to the Z06.
A little Dodge on Dodge action is next with a bolt on Gen V Viper making roughly 600 whp taking on the Challenger Hellcat. The Viper weighs 1300 pounds less and it shows. This is the closest race but the Viper pulls.
A stock Charger Hellcat is provided as a baseline run next. The tuned Challenger on E85 is clearly making more power as it pulls.
A ~700 whp Charger tries its luck next and this run is solid between the two.
A Nissan GTR with a turbo upgrade is next and it just easily pulls. This car should run the Z06 or the Procharged C7.
How about a Procharged Coyote? The Hellcat get a jump and opens up a lead but the Mustang starts to claw back. They run again and with a more even start the Mustang GT pulls.
We honestly expected a bit more out of a bolt on Hellcat on E85 on the highway.

We've been involved in the testing of a nifty new product called Dragy. It's a small high speed GPS device that interfaces with your phone or mobile device via BlueTooth and allows you to accurately compute performance metrics like 0-60, 1/4 mile & trap speed, 60-130mph, 100-200kmh, etc. The resulting run files compute and validate slope, and spit out in a little graphic ready to analyze, share, etc.
You charge it using a mini-USB port, with the charge lasting a few days (it only wakes up when connected to app), and then throw it on the dash and open the app when you want to start recording runs. It's magnetic so there are slicker mounting options available, but I haven't found them necessary on our test cars. I just throw it up in the corner of the windshield.
We tested them at the latest Shift Sector and No Fly Zone 1/2 mile events and were very pleased with the accuracy and flexibility of the system. A few screen shots from my testing below.
There are a few thousand in use in Asia with great success and we're helping introduce it to the English speaking market. The free Dragy app will be posted to the play store and apple store within a few days. If you happen to get the device before the app is posted just email us and we can send a link for it.
Anyway much more info to follow, including their app based tuner leader board and other slick features, but I know you guys are going to love this thing.
Wanted to make a comparison video but right now its Dragy 1, VBOX 0

Is anyone keeping score of how many people have been scammed or stolen from by Dime Racing up to this point? BoostAddict is doing its best but admittedly there are so many horror stories to sort through it is tough to keep track.
The latest victim to come forward is Meister Werke Design + Technik or MWDesigntechnik.
What happened? They ordered a very expensive Super Trofeo Race aerodynamic kit for their Huracan for roughly $30k. They were strung along and never received the kit. The money was taken of course.
This comes in the wake of Dime being sued by multiple parties, Brian McLevis' Huracan horror story, ripping off Deeds Racing, oh and the Vehicle Virgins Huracan horror story.
These guys sure love taking advantage of Huracan owners, eh? Easy targets with money so it makes sense from the scammer perspective.
If only someone had warned people? Oh, that's right, BoostAddict did.
It's a shame to read that yet another person was taken advantage of:

Mercedes styling is really blending together these days. The C, E, and S basically are all the same design just offered in small, medium, or large. The new CLS-Class is the first real departure but the front headlights almost seem too sharp and angular.
The familiar CLS silhouette is there yet somehow this design does not come off as instantly flattering or familiar.
Perhaps we need to wait for the official photos as this is an early leak.
The interior is spectacular as to be expected since it essentially just samples the W213 E-Class.
Do you love it or hate it?

Ambitious. This sports car from Saleen which they are calling the S1 sounds great on paper. A 450 horsepower turbocharged 2.5 liter four-cylinder is under the hood. Where are they getting this engine from? Good question.
As is what transmission the car will have. It is pictured with a manual but beyond that nothing is specified. Manual only? 6-speed? Well?
Let's assume they meet the targets and this is indeed a 2700 pound mid-engine sports car for $100k offering 450 horsepower. That would have no rival in the marketplace. The closest thing would a Porsche 718 Boxster GTS which suddenly looks heavy in comparison.
The Porsche might be heavier but it has a few things going for it. For one, it exists. Secondly, it is far more polished.
The S1 looks like a kit car. Everything about it comes off as a kit car. We have no real specs, no real testing, and no real car on the market.
Hopefully Saleen pulls it off.

The new 2019 Corvette ZR1 LT5 motor illustrates the point well that direct fuel injection on its own is not the best choice for a performance car. You will notice an increasing trend of high performance cars coming to the market with dual fuel injection.
That means both direct and port fuel injection systems. Why both? Because direct injection quickly becomes a liability.
The technology spread due to efficiency benefits not because it was better for performance. Want to disagree? Tell it to McLaren who for some reason opted not to equip the McLaren 720S M840T V8 which is absolutely vaporizing all challengers with direct fuel injection.
The issue is not only do you need strong pumps capable of huge pressure the injection window shortens with RPM. That makes it a challenge to provide enough fuel at higher rpm ranges. This is exacerbated as power as added.
Let's assume for a moment you buy a Ferrari 458 which has a direct injected motor that revs to 9k rpm. You might be saying, what is the problem? Well, try running ethanol through the motor. As ethanol contains less energy than gasoline while at the same time offering higher octane and cooling benefits you need to flow more of it through your fuel system. The direct injection system quickly taps out. It only gets worse if you add power.
Port fuel injection does not have the same injection window or pressure issues. This is probably why McLaren does not use it on its 8000-8500 rpm motors. This is probably why Ford does not use it on the 8200 rpm GT350 Voodoo V8. This is probably why BMW M did not equip the S65 V8 or S85 V10 8250+ rpm screamers with direct injection.
Manufacturers building performance engines today with direct injection are increasingly offering dual injection systems with port fuel injection. Why? To alleviate stress on the direct injection system and offer fueling headroom say with modern ethanol blends. It also reduces carbon deposits.
There are pluses and minuses to both approaches. Direct injection allows motors to run at higher compression before detonation on pump fuels. This obviously provides a power and efficiency benefit. The cooling effect of direct injection is due to fuel droplets going through a phase change from liquid to gas and becoming an ignitable vapor that can be mixed with air and detonated by the spark plug.
Heat is absorbed during this change providing a cooling effect which will allow a direct injection motor to run leaner. Again, this provides an efficiency benefit when it comes to fuel use.
Port injection allows air flowing through the intake manifold to cool before reaching the combustion chamber while direct injection provides its cooling benefit in the chamber itself.
Port injection also does not require the high injection pressure and it does not have the limited injection window which means it is easier to flow far more fuel. You can see how combining these two technologies provides the benefits of both and minimizes the downsides.
Just look at the performance motors that recently entered the market with dual fuel systems:
Chevrolet LT5
Audi 2.5 TFSI
Audi/Lamborghini 5.2 V10
Bentley W12
Ford 3.5 Ecoboost
There are other motors with dual injection not listed there but you get the idea and more are on the way.
It is interesting to note that many enthusiasts on the various BoostAddict sites with direct injected motors who add power look into adding supplemental port injection systems.
It is ironic that getting away from port injection quickly leads them right back to port injection once they start to add power and run ethanol.
Factory dual-injection tends to provide the best of both worlds.

The AMG M177/M178 4.0 liter V8 is familiar to most Mercedes-AMG enthusiasts as the engine architecture sees duty in the C63 and AMG GT. The new 2018 Mercedes-AMG E63 and E63 S gets an M177 variant as well but with a major difference.
That difference being a new manifold and turbochargers featuring twin scroll turbo technology. The E63 is quite simply much more powerful due to this change than its C63 sibling.
The motor being in a higher state of tune from the factory also means it is more difficult to extract power out of. Yet, Weistec is able to get some very nice gains on their all wheel drive Dynojet on 91 octane pump gas:
You will notice the majority of the increase in the mid-range. At 4500 rpm wheel horsepower is up by 80 and torque is up by 93 lb-ft at the wheels.
Peak horsepower increases from 568 at the wheels to 625. Just with Weistec software alone.
Some will be saying the M157 shows larger gains over stock which is true but when tuned the M177 actually offers more torque and top end horsepower over its larger previous generation AMG engine sibling.
Weistec's W213 ECU upgrade starts at $2995.00: http://weistec.com/all/e/e-63/2018-present-4matic-w213-m177/ecu-calibration/m177-ecu-upgrade-w213.html
Key Features:
Improved Throttle Response
Optimized Fuel, Spark, and Boost
50+ Wheel Horse Power Peak to Peak Gains with Air Filters
Up to 75HP gains in the mid range
Start Stop Disabled (for Race Vehicles)

Mercedes-AMG is essentially offering the same engine architecture in various state of tune. The M176, M177, and M178 V8 motors are all the same basic design and engine family but there are differences based on the application.
For example, the M178 gets a dry sump oil lubrication system as AMG GT owners are more likely to track their cars. Plus, there is a large price premium so it makes sense the top model gets all the goodies.
The C63 and E63 both have an M177 4.0 liter twin turbo V8 yet the output is very different between the two. How do they differ?
W205 C63 S
Displacement: 3982cc
Bore x Stroke: 83mm x 92mm
Horsepower: 503
Torque: 516 lb-ft
Redline: 7000 rpm
Compression Ratio: 10.5:1
Boost: 17.4 psi
W213 E63 S
Displacement: 3982cc
Bore x Stroke: 83mm x 92mm
Horsepower: 603
Torque: 627 lb0ft
Redline: 7000 rpm
Compression Ratio: 8.6:1
Boost: 21.8 psi
What should immediately strike you is that the E63 S has higher boost pressure but also lower compression. Much lower compression. Why? Well, because Mercedes-AMG is cramming in a lot more air. It is the same compression ratio as the M133 four-cylinder in the CLA45 AMG.
The main difference is that compression ratio and the turbochargers. As the E63 S is 500 pounds heavier plus sending power to all four wheels courtesy of 4Matic it needs much more power and torque to move it. Especially considering that it is priced above the C63 in the lineup.
The new twin scroll turbochargers ensure the E63 S is making more power and torque. There is a bit of a trade off in lag but past 3000 rpm until redline there is a massive difference in area under the curve in favor of the E63 S:
The Renntech tuned E63 S is making nearly 120 more horsepower than the Renntech tuned C63 S.
Maybe swapping E63 turbos and manifolds onto the C63 will become popular?
The E63 also gets new pistons as already highlighted plus a new intake manifold and intercooler design.
There you have it.

Bought it the other day and it should be arriving any time now. Really looking forward to playing Forza 7!
Really the first thing that is going to make my 4k TV worth owning.
Anyway, anyone else buy one? Maybe time to get the Xbox Live name list going on.
